Prospective Trial of Autologous Platelet Rich Plasma in Aortic Surgery

November 15, 2016 updated by: Hongwen Ji

Prospective Randomized Trial of Autologous Platelet Rich Plasma in Reducing Allogeneic Transfusions During Aortic Surgery Under Deep Hypothermic Circulatory Arrest

The purpose of this study is to determine whether autologous platelet rich plasma (APRP)is effective in reducing allogeneic blood transfusions during aortic surgery using deep hypothermic circulatory arrest.

Design Details

  • Primary Purpose: Prevention
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: APRP group
APRP group is performed autologous platelet-rich plasma harvest technique before administration of heparin to the patient,the red blood cell(RBC) component is retransfused to the patient when the RBC transfusion protocol is reached,and the autologous platelet-rich plasma is transfused to the patient immediately after heparin is neutralized with protamine.
Device: Autologous Platelet-Rich Plasma Harvest Technique
15 to 20 mL/kg of whole blood is collected before the administration of heparin from a large-bore central venous access,and is separated into red blood cells component and autologous platelet-rich plasma component by an autologous transfusion system(Sorin Group Electa Essential; Sorin Group Italia, Milan, Italy).
Other Names:
  • neutralizing heparin with protamine
No Intervention: control group
APRP group receive no autologous platelet-rich plasma harvest technique.
